Objective To investigate the risk factors of wound complications following the abdominal aorta balloon occlusion in order to provide the basis for the preoperative management and reduce postoperative complications.Methods Two hundred and sixty-one patients with the sacral tumor aged over 18 were selected as subjects who hospitalized at Peking University People's Hospital from January 2006 to December 2012.All subjects were underwent sacral tumor posterior resection operation after occlusion of the distal abdominal aorta.Patients were divided into two groups according to the existence of postoperative wound disorder.The general information of the patients was collected including intra-operative data and post-operative data.SPSS19.0 software was applied for statistic analysis Results Among 261 cases,89 cases were with incision complications,and the incidence of complications was 34.1％ (89/261).There was no significant difference regarding of age,weight,preoperative complications (P ＜ 0.05).Compared with that of no complications group,operation time of wound complications group was longer ((218.27 ± 72.08) min vs.(197.40 ± 53.92) min,P =0.046),and intra-operative bleeding was more ((2368.0 ± 1984.7) ml vs.(1701.6 ±958.8) ml,P =0.000),as well as a longer balloon occlusion time ((78.0 ± 23.8) rain vs.(65.2 ± 17.8) min,P =0.005).Moreover long hospitalized periods was in wound complications group ((47.6 ± 26.3) d,vs.(26.7 ± 9.0) d,P ＜ 0.05).Single factor analysis showed that the factors including operation time,intra-operative bleeding volume,time and times of balloon occlusion balloon occlusion were related to postoperative wound complications.Non conditional logistic regression analysis shows that factors of the balloon occlusion time(OR 1.028,95％ CI 1.012-1.045,P =0.001) and block number(OR 6.266,95％ CI 1.186-33.119,P =0.031) were related to the wound healing following balloon occlusion the abdominal aorta.Conclusion The risk factors of wound complications following the abdominal aorta balloon occlusion included occurrence balloon occlusion time and blocking times.That single balloon occlusion with 60 min reduced wound complication rate.

Objective To investigate the significance of anti-SmD1 antibody and other auto-antibod- ies in systemic lupus erythematosus(SLE).Methods Forty-four SLE patients and 136 other rheumatic dis- eases patients were studied.The later group included Sj(?)gren's syndrome,undifferentiated connective tissue disease,ankylosing spondylitis,and rheumatoid arthritis.Immunoblotting was used to measure,the anti-SmD1 antibody,ANuA and anti-SSA60 000 antibody.ANA and anti-dsDNA were detected by indirect immunofluo- rescence,immunodotting was used to measure the anti-Sin antibody.Results The seropositive rate of anti- StuD1 was 47.7% in SLE patients.It was much higher than that of anti-Sm(P

Objective To analyze the antiangiogenic effect of stereotatic radiosurgery (SRS) in rat C6 gliomas using MR perfusion imaging(PWI) technique. Methods Twenty rats implanted with C6 glioma cells in the brain were randomly assigned into group A (without any therapy) and group B which underwent SRS therapy 4 weeks after implantation. PWI was performed to measure the regional cerebral blood volume (rCBV) and regional cerebral blood flow (rCBF) in tumor's region before therapy in all rats and 1 week later in group B. PWI sequence was applied pre-and post--inhalation of a mixture of 10% CO_2 and 90% air. rCBV and rCBF were analyzed. PaCO_2 and blood PH values were monitored before and aftermixed gas inhalation. All the MRI examination were car-ried out at a 3.0T magnet. The rats were sacrificed after MRI examination. Microvessel density (MVD) and number of mature ves-sels (with muscle layer) were measured histologically using immunohistochemical staining for factorⅧ and smooth muscle actin (SMA). PWI data, and pathological results were analyzed statistically. Results The size of tumors in group B remarkably de-creased with obvious necrotic area in the center 1 week after SRS therapy. PH value decreased and PaCO_2 increased significantly af-ter mixed gas inhalation. Blood gas data changes in group B were not significantly different from that in group A. The rCBV and rCBF of tumor's core in group B declined greatly after SRS treatment. The necrotic area was dark in rCBV and rCBF maps, that suggested no blood supply in this region. After therapy, the changing rate of rCBV and rCBF pre-and post-inhalation of gas in group B was greater than those in group A. The MVD of tumors in group B after treatment was sta-tistically less than that in group A. The number of SMA positively stained vessels in group B was nearly equal to that in group A. The percentage of SMA(+)/MVD in group B was significantly higher than that in group A. Conclusion SRS can inhibit the angiogenesis of rat C6 glioma, however vessels with smooth muscle cells are insensitive to SRS.

Objective To evaluate four tumor markers of insulin-like growth factor 1((IGF-1), CEA, cytokeratin fragment antigen 21-1 (CYFRA21-1), neuron-specific enolase (NSE) for the diagnosis and prediction of treatment response in human lung cancer. Methods Serum samples were taken from three groups: 91 patients with lung cancer, 30 healthy adults and 15 patients with benign pulmonary diseases. Serum IGF-1 was assayed by radioimmunoassay and CEA, CYFRA21-1, and NSE by electrochemiluminescence immunoassay. The differences among the three groups were determined by Kruskal-Wallis one-way analysis of variance (ANOVA) and with Mann-Whitney rank-sum test. Diagnostic efficacy was evaluated by ROC curves. Results The four serum tumor marker levels were significantly higher in lung cancer group, as compared with the benign and the healthy (IGF-1:χ2=26.95,P<0.001, CEA:χ2=49.11,P<0.001; CYFRA21-1:χ2=40.63,P<0.001; NSE:χ2=14.76;P<0.001). The diagnostic sensitivities of IGF-1, CEA, CYFRA21-1 and NSE was 75.6% (34/45), 53.3% (24/45), 66.7% (30/45) and 42.2% (19/45) respectively for lung cancer. The diagnostic sensitivity of IGF-1 combined with CYFRA21-1 was 95.5 %( 43/45) and that of IGF-1 combined with CEA and CYFRA21-1was 97.8%(44/45). Only IGF-1 and CYFRA21-1 showed significant changes before and after treatment (IGF-1: χ2=5.99,P=0.014; CYFRA21-1:χ2=4.99, P=0.025) in cancer group. Conclusions Serum IGF-1, CEA, CYFRA21-1 and NSE are all valuable for lung cancer diagnosis and the combination of those parameters can enhance the diagnostic efficiency. Serum IGF-1 and CYFRA21-1 may also be useful for evaluating the treatment response in lung cancer.

Objective　To explore the relationship of defense style and mental health in student of middle school. Method 203 middle student were investigated with Defense Style Questionnaire (DSQ) and Symptom Check List-90 (SCL-90). Results There were no significant difference for 4 factors of DSQ in man／female and advance middle school or not(P>0.05); there were significant difference for immature defense mechanism and middle type factor ,and conceal factor in high-symptom score team with that of low-symptom sore team(P<0.01) and it is positive-correlation with each factor-score and total score of SCL-90. Conclusion School and family need to pay attention to the higher correlation in the total score of SCL-90 with immature defense mechanism and middle type factor and conceal factor.

[Objective] To answer the following questions:① For Oncomelania snails collected two years apart from the same locality,has there been genetic divergence?②How much experimental error has there been in studying subsets of these populations? ③As this is an unstable population,what has the net effect been on Hardy-Weinberg equilibrium(Hwe)?[Methods] Allozymes were studied using horizontal starch gel electrophoresis.Data collected from numbers of experiments were conapiled.Data from each collection were divided into two equal subsets based on chronology of the experiments.Thirty-four loci were studied using 72 to 180 snails per subset.[Results] The mean number of alleles per locus ranged frcra 1.5～1.9.With each consecutive subset,the 96 polymorphic loci dropped from 38.2 to 17.6.The mean heterozygosity was very low:0.033 to 0.049 and not significantly different from Hardy-Weinberg expectations.Ten loci and 11 alleles exclusive to the first group were eliminated from the overall study reducing the number of polymorphic loci from 19 to 10.There were significant departures from Hwe at five loci having a substantial number of individuals for each allele.Nei's and Wright's D were 0.003±0.001 and 0.054±0.006 respectively.[Conclusion] ①There were significant errors seen primarily in the results scored' in the earliest experiments.②These earlier errors involving scoring difficult to resolve loci,and interpretation of rare alleles that were not found in later experiment had no significant effect on overall genetic distance.③The use of Wright's D for closely related populations is explained.Results with Nei's D indicated no significant difference among the four subunits; Wright's D yielded significant difference between the collections made two years apart,attributed to the annual flooding of the Yangtze River mixing snails from different localities.④ Major polymorphic loci were not in Hwe as predicted using the unstable population model.⑤One must study 25 or more individuals to find relatively rate alleles and study population genetics.

Objective To examine the distribution of flurbiprofen axetil in cerebral-spinal fluid (CSF) by determining the CSF concentration of flurbiprofen after iv administration. Methods Seventy-two ASA Ⅰ or Ⅱ patients of both sexes aged 18-75 yr weighing 54-82 kg undergoing spinal or combined spinal-epidural anesthesia for lower extremity or lower abdominal surgery were studied. Flurbiprofen axetil 1 mg/kg was injected intravenously.CSF 2 ml and venous blood 3 ml were obtained simultaneously every 5 min after iv injection for 45 min (T1-9 ) for determination of flurbiprofen concentration using high performance liquid chromatography, and the CSF/blood flurbiprofen concentration ratio was caculated. Results Flurbiprofen was not detected in CSF at T1,2 after iv injection in 3 and 4 patients. The CSF flurbiprofen concentration was significantly higher at T4-9, and CSF/blood flubiprofen concentration ratio higher at T5-9 than at T3 ( P ＜ 0.05). There was no significant difference in CSF flurbiprofen concentrations among T4-9 ( P ＞ 0.05 ) Conclusion Flurbiprofen is detected in CSF after iv injection, the CSF flurbiprofen concentration peaks at 20 min after iv injection and it lasts until 45 min after iv injection.

Objective To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on sedative efficacy during induction of anesthesia with propofol.Methods Patients,of ASA physical status Ⅰ or Ⅱ,aged 21-69 yr,scheduled for elective thyroid surgery,were randomly divided into 2 groups using a random number table:control group (group C) and TEAS group.TEAS was applied to bilateral Hegu and Neiguan acupoints for 30 min.The frequency was 2/100 Hz,wave length was 0.2-0.6 ms and the intensity was maintained at about 8-12 mA according to the current that could be tolerated.Induction of anesthesia was started at the end of TEAS.Sequential method was used to determine the median effective target plasma concentration (EC50) of propofol causing loss of consciousness in each group.The initial target plasma concentration of propofol was 3 μg/ml.BIS value was recorded every 30 s within 5-8 min after loss of consciousness and the average BIS value was calculated.It was considered to be positive response when the average BIS value was below 50.The target concentration of propofol was decreased/increased by 0.3 μg/ml in the next patient.Results EC50 of propofol causing loss of consciousness was 3.08 μg/ml in group TEAS,and 3.70 μg/ml in group C,and there was significant difference between the two groups.Conclusion TEAS can enhance the sedative efficacy during induction of anesthesia with propofol in the patients.
